Diablo: Greatest Game of All Time

Diablo was chosen by Gamespot as the Greatest Game of All Time with a review of how Diablo has influenced other games:

Gamespot: The game birthed the action-RPG genre as we know it, spawning dozens of copycats on the PC in the years following its release. Consoles even began to get into the act with Baldur’s Gate: Dark Alliance, which was very heavily influenced by Diablo. To this day, Diablo is used as a point of comparison for any game that involves simple point-and-click combat, character development, hordes of monsters, massive levels, and collectible loot and equipment.
